New 16-litre Volvo Penta Tier 3/Stage 3 diesel engine

The new TAD1650VE diesel engine is Volvo Penta’s latest and most powerful engine for off-road and stationary applications. The engine combines impressive power and torque with exhaust emissions that comply with the world’s most stringent regulations: EPA/CARB Tier 3 and EU Stage 3.

The TAD1650VE is based on the successful state-of-the-art concept of the Volvo 9- and 12-litre engines. The design features Volvo Advanced Combustion Technology (V-ACT), which results in low exhaust emission levels. With a swept volume of 16.1 litres, the TAD1650VE delivers tremendous power and impressive torque while giving excellent fuel economy, high reliability and durability.

Tier 3 emission levels
The Volvo electronic system (EMS2) has been further upgraded for this engine with increased processing power. Together with improvements in air and fuel management this gives extremely fast response to throttle opening but with very low transient smoke, easily meeting the overall EPA/CARB Tier 3 and EU Stage 3 off-highway emission regulations.

As part of the V-ACT system, the engine is equipped with internal exhaust gas recirculation. An electro hydraulic control system regulates valve actuation to allow a small amount of exhaust gas to
be fed back into the cylinder, thereby lowering peak temperatures and reducing the formation of NOx.

Fuel quality can sometimes prove to have harmful effects on certain designs of emissions certified engines. Despite being designed to meet EU and US emission standards, the TAD1650VE is manufactured with a worldwide specification and is designed to operate using all commercially available fuel qualities.

Massive power in compact size
The engine is a direct-injected, four-stroke, turbocharged, charge-air-cooled diesel with mechanically actuated, electronically controlled unit injectors. It has a rear timing gear train, giving it a shorter length and improved noise characteristics.

The TAD1650VE produces 400 kW at 1800 rpm with a virtually flat torque curve of 2,500 Nm over the speed band 950-1500 rpm and peaking at 2,550 Nm at 1400 rpm.
